Method of calibrating a force balance

摘要

A calibration system and method utilizes acceleration of a mass to generate a force on the mass. An expected value of the force is calculated based on the magnitude and acceleration of the mass. A fixture is utilized to mount the mass to a force balance, and the force balance is calibrated to provide a reading consistent with the expected force determined for a given acceleration. The acceleration can be varied to provide different expected forces, and the force balance can be calibrated for different applied forces. The acceleration may result from linear acceleration of the mass or rotational movement of the mass.

1. A method of calibrating a force balance, the method comprising:
providing a force balance to be calibrated; operably interconnecting a mass of a known magnitude to the force balance whereby acceleration forces acting on the mass are reacted solely by the force balance; causing the mass to accelerate at a known rate while the mass is moving to generate a force on the force balance; determining an expected force acting on the force balance based on the magnitude of the mass and the known acceleration of the mass; adjusting an output of the force balance to provide a measured force that is substantially equal to the expected force.
